Overview
MSP430FR2422IPW16 from Texas Instruments is a 16-bit RISC ultra-low-power mixed-signal microcontroller featuring 7.25 KB FRAM program memory, 256 B information FRAM, 2 KB SRAM, an 8-channel 10-bit ADC, and dual eUSCI modules (UART/IrDA/SPI/I²C) - deployed in battery-powered sensing applications such as portable medical devices and industrial sensor nodes.
For engineers reviewing the MSP430FR2422IPW16 datasheet, MSP430FR2422IPW16 pinout, MSP430FR2422IPW16 application, or MSP430FR2422IPW16 equivalent, key selection criteria include its 16-pin TSSOP package, 1.8–3.6 V supply range, LPM3.5 RTC operation at 710 nA, FRAM endurance (10¹⁵ writes), and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430FR2422IPW16 integrates a 16-MHz DCO with FLL, on-chip REFO (32 kHz), VLO (10 kHz), and MODOSC, enabling flexible clock tree configuration with ±1% MCLK accuracy at room temperature. Its power management supports six low-power modes including LPM3.5 (RTC active, 710 nA) and LPM4.5 (shutdown, 36 nA).
Peripherals include two Timer_A3 modules (each with three capture/compare registers), a 16-bit CRC engine, 15 GPIOs (11 usable in TSSOP-16), and analog subsystems with internal 1.5-V reference and 200 ksps sample rate - all mapped to a unified FRAM memory space supporting ECC and configurable write protection.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2433IPW16 | 8 KB FRAM, 2 KB SRAM, same package; adds comparator and enhanced timer features. | Required for designs needing analog window comparators or additional capture/compare channels. | Select when higher memory headroom or analog comparator functionality is needed - no PCB change required. |
| STM32L011K4T6 | 32-bit ARM Cortex-M0+, 16 KB Flash, 2 KB SRAM, 12-bit ADC; operates down to 1.8 V but lacks FRAM. | Suitable where 32-bit processing, larger code space, or certified crypto peripherals are prioritized over FRAM endurance. | Choose for projects requiring ARM ecosystem tooling or certified security features - requires layout revision due to different pinout and power sequencing. |
Compared with MSP430FR2433IPW16, the MSP430FR2422IPW16 offers identical pinout and lower cost for simpler sensing tasks; versus STM32L011K4T6, it delivers superior write endurance and lower active-mode current but lacks 32-bit compute and Flash-based firmware update flexibility.

FAQ
What is the maximum operating frequency of the MSP430FR2422IPW16?
The MSP430FR2422IPW16 supports a maximum system clock (MCLK) frequency of 16 MHz, achieved using the on-chip digitally controlled oscillator (DCO) with frequency-locked loop (FLL) stabilization. This frequency is fully supported across the 1.8–3.6 V supply range and enables real-time processing of sensor data without external clock sources.
Does the MSP430FR2422IPW16 support hardware debugging?
Yes, the MSP430FR2422IPW16 supports hardware debugging via the Spy-Bi-Wire (SBW) interface using pins SBWTCK (pin 3) and SBWTDIO (pin 4). It is compatible with TI's MSP-FET, LaunchPad development kits, and third-party JTAG/SBW debuggers - no external debug header is required for basic programming and real-time debugging.
How many analog input channels does the MSP430FR2422IPW16 ADC support?
The MSP430FR2422IPW16 integrates an 8-channel, 10-bit successive approximation register (SAR) ADC. In the TSSOP-16 package, five analog inputs are accessible: A0 (P1.0), A1 (P1.1), A2 (P1.2), A3 (P1.3), and A4 (P2.2). Channels A5–A7 are not routed to this package variant per Table 7-2 of the datasheet.
What is the standby current consumption of the MSP430FR2422IPW16 in LPM3.5 mode?
In LPM3.5 mode with the real-time clock (RTC) active and a 32.768-kHz crystal, the MSP430FR2422IPW16 consumes 710 nA (typical) at 3 V and 25°C. This ultra-low current enables multi-year operation on small coin-cell batteries while maintaining precise timekeeping for periodic wake-up events.
Can the MSP430FR2422IPW16 operate from a 1.8-V supply?
Yes, the MSP430FR2422IPW16 is fully specified to operate from 1.8 V to 3.6 V. However, minimum supply voltage is constrained by SVS (supply voltage supervisor) thresholds - at 1.8 V, SVS must be configured to avoid unintended resets. All peripherals, including the 16-MHz DCO and 10-bit ADC, function correctly within this range.
